A new documentary is set to lift the lid on life behind bars at Norwich prison.

The programme, Her Majesty's Prison: Norwich, will provide a fly-on-the-wall type insight into the harsh realities of life at the Knox Road jail which houses more than 750 adult inmates and young offenders.

Made by Wild Pictures, producers of the acclaimed ITV prison series HMP Aylesbury, Strangeways and Wormwood Scrubs, the programme will also demonstrate how inmates' contact with their families can be a lifeline while inside.

Most of the 2,500 new prisoners who pass through its gates every year are husbands and fathers and the new ITV show will feature a number of men who are hoping their families will help them turn their backs on a life of crime once released.

One of those to be included in the ITV1 show, which will be shown at 9pm on Wednesday<4>is Rocky Gamble, 30, a father of two who was last month jailed for eight years after admitting conspiracy to supply class A drugs.

For Gamble, who was waiting to be sentenced when the film was shot, it was to be his sixth custodial sentence.

He told the programme 'I just don't want to be involved in it anymore. Do you know what I mean? It's a mug's game.'

Of his partner and children, he said: 'Sometimes I wonder why she does wait for me. She's a good girl. I'm going to have to sort myself out. I can't lose her and the kids - they're my world.'

Visits to the prison, although important to inmates and their families, can also pose a security risk for the jail and the programme shows how some people coming to the prison are found to have drugs on them.

But one prison officer reveals it is not just adults that act as carriers with some visitors even secreting contraband on children and young babies.

Her Majesty's Prison: Norwich is aired on ITV1 on Wednesday at 9pm.
